Patented Oct. 15, 1929 UNiTED STATES iastate PATENT "OFFICE JAMES THOMAS JOHNSON, OIF NASHVILLE, TENNESSEEr-ASSIGNOR OF'ONE-HALF TO EDWIN F. BOBBITT, OF lNASHVILLE, TENNESSEE WINDOW SCREEN Application filed November 26, 19727. Serial No. 235,867.

This invention relates to an improved win- -dow screen structure, and it has particular' reference to a structure of this class, wherein the screen is constructed for swinging movement in the window frame.

More particularly, the invention has reference to a so-called half-screen which is constructed and mountedfin such a way as to permit it to occupy either a lower position, or an upper position, thus making it permissible to move the screen from the lower half of the window frame, at night, up to the top half, and permitting the upper sash to be lowered and the window blinds raised to promote free ventilation.

The particular construction an-d other advantages of the invention will become more readily apparent from the following description and drawings.

In the drawings Figure 1 is an outside elevational view of a window frame showing the improved screen located in the upper half of the window frame above the hingedly mounted shutters.

Fig. 2 is an inside view, of certain of the features shown in section, with the other features removed for clearness, taken on the line 2*2 of Fig. 4.

Fig. 3 is a horizontal section taken approximately upon the plane of the line 3-3 of Fig. 1.

Fig. Fig. 1.

Fig. 5 is a view like Fig. 4, showing the screen down and ready to be positioned in the lower portion o'f the window frame.

Fig. 6 detail view of one of the extensible retaining links forming an important part of the invention.

Referring now to the drawings in detail, and particularly to Figs. 4 and 5, it will be seen that the reference character 7 designates generally a window frame in which slidable sashes are mounted in the customary manner. rIhe upper sash is designated by the numeral 7 and the lower one by the numeral 9. The screen, which is of the half-type, is generally designated at l0 and the swingable hingedly mounted shutters by the numerals 11.

The shutters as shown in Fig. 1, preferably 4 is a vertical section on the line 4-4 of occupy the lower half of the window frame. I also wish to call attention tothe cross strips providing a stop and carrying a small. eyebolt 13. I also call attention to al small eye bolt 14'in the window frame just above the lower rail of the upper sash. The window screen comprises a frame l5, whose vertical side bars are formed with grooves along theV marginal edges as indica-ted better in Fig. 3..

Fastened on the frame is a customary wire mesh-screen 16 held in place by moldingl. Therev is a small hook 18V carried by the top rail of the screen frame, this being adapted for connection with the eye bolt l13. In addition, there are hooks 19 fastened to the verticalside rails of the screen frame, these being intended to be detachably connected with the eye bolt 14. l

I employ a pair of duplicate retaining links, these being generally designated by the numerals 2O and each including a tube 21 in which a rod 22 isA slidable. The tube is flattened at its upper end and pivotally connect-ed to the window frame as at 23, and the rod is pivotally connected in the grooved side bars of the screen frame.

Adjustment between the rod and screw members is maintained through the use of the set screw 24. It is obvious that the screen and links may occupy either the position shown in Figs. 4 or the position shown in Fig. 5. A

In either position, the screen bears against the cross piece 12. When in the lower position, shown in Fig. 5, the screen is of course swung completely into the window frame, and is hooked in place by the hook 18 which is then engaged with the small eye-bolt 18. When in the raised or elevated position shown in Fig. 4, it is held in place by the hooks 19 which are engaged in the eyes 14. In either position, it is held partly by the eXtensible links. In additon, the links constitute the means for facilitating the movement of the screen from one position to another.

From the foregoing, it will be seen that I have evolved and produced a half screen which can be used either at the top or bottom, thereby taking the place of a whole screen. The screen can be set at any angle,

when washing windows and when dusting screens to prevent the dust from being on the inside of the house.

When the screen is at bottom, remove the hook 18, and push the top out. This automatically unlocks the screen so that it can then be swung up. This screen has the advantage of the old style soreen'being held in place both at the top, center, and bottom. When the screen is at the bottom, it is held in place at the top end by hooks, inthe center by the invisible hanger and hinged links, and at the bottom by the small dowel pins iitting into small sockets.

The screen is thus prevented from warping. The screen does not interfere with the use of half shutters, as the screen ,is never in the wey of the shutters. When the shutters are Closed, the yscreen is at the top. The links I are adjustable permitting the screen .to be used in different types of window frames.

Havingthus described :my invention, .what I claim as new is z- In Combination `with a halt' screen embodying a frame including a top, bottom and side pieces, and having one of said side pieces formed along its outer marginal edge and on its inner side with a groove, a retention and att-aching link eonnected to'- said last mentioned vside member ,and foldable into said groove, and said link vembodying a tube apertured and iiattened at its outer end, and a rod telescoping into said tube, together with aset screw carried by said tube and engageable with vthe rod.

In ltestimony*whereof I aiiix my signature.

JAMES THOMAS JOHNSON.
